I woke up staring at the ceiling, looked and read my watch as 00.50.
and not a clue as to where I was!
yes, I gathered it was my room, but where? did I live in an apartment...? if so, where is this apartment, looks like in an old building...
eventually the right info dripped down, but how uncomfortable was that! also, after wandering into the kitchen and back I looked at my watch and it had changed its mind and was showing 10.45...
conclusion: for me the 2 sleeps method needs work. here it is 02.22
